ESP32 bluetooth LE peripheral scan invisible to iOS 16, works with iOS 15

Dear Quorum, please allow me to turn to you with an extremely weird issue. My client and I work on an ESP32 based product which communicates via Bluetooth LE. On both Android and iOS 15, the peripheral can be seen by both our MAUI application and the Bluetooth LE scanner available in the store. Sadl...

Re: LyraT 4.3 - need three PWM GPIOs, but they behave weirdly

Hello,
to report in: it now works perfectly. We had an issue in our algorithm which caused ZERO to be output at the PWM for some time, causing the behavior.

My apologies.

Re: ESP-IDF hangs on windows 10

Hello, confirming same problem. Solution: a) quit installer b) open command line, run failed command like so: C:\Espressif\tools\idf-git\2.39.2\cmd\git.exe -C C:\Espressif\frameworks\esp-idf-v4.4.4 submodule foreach git reset --hard c) rerun installer, tell it to use the IDF folder. Log, in case any...

Re: esp_ble_gatts_set_attr_value,can not work!

Attention! The handle table is initialized ASYNC, as in, some time after the main stack is inited.

I solved this problem by updating the BLE store only on device connect.

Also, keep in mind that the method returns ESP_OK even if the handle is unitialiyed, in this case it just bins the result.

LyraT 4.3 - need three PWM GPIOs, but they behave weirdly

Esteemed Quorum, a small question: for an application, we would like to generate PWM output from a ADF pipeline object. Our hardware is a LyraT 4.3, we use IDF version 4.4. All jumper settings are set to enable JTAG on the JTAG connector. The initialization is done like so: #define LEDC_GPIO 14 ledc...

Re: ESP-ADF and ESP-DSP

Sorry for thread necro. But I had similar issue.

If you have the env var ESP_IDF set, all kind of weird shit happen. For ESP_ADF based project, ONLY ESP_ADF var may be set.

Re: Pipeline element FFT returns strange values

Hello, we managed to get forward a little bit. This now leads to somewhat workable data - aka if we do not talk to the unit, it does not show a spectrum: int16_t DspBuf[4096]; static int _tams_process(audio_element_handle_t self, char *in_buffer, int in_len) { ESP_LOGI("ICY", "FFT for %i len data bu...

Pipeline element FFT returns strange values

Hello Folks, and it is my turn to come here. After a disastrous run with a BlueNRG based solution, my customer and I are trying to rescue what is left of the project. We decided to settle on the ESP-ADS; and use a LyraT 4.3 as our development board (nice hardware). Sadly, we have a problem. Our work...
